About the movers.
We know that they only come back at the end as per L&P post.
As
KillJoys said multiple times this could be the (bad) end of the FW route, with the marriage falling apart etc etc.
It's strange, though, that the same truck is in the teaser, it's difficult to think of an oversight considering how he cares about the details. If it is so, or just a coincidence (e.g. an enterprise with multiple similar trucks), ok false alarm.
Now, let's consider the alternative (just for the fun of speculation).
They will come back at end, likely to move out the family. Will there be more that just moving furnitures? Will they be another if not the final piece of the FW route, with Sophia at that point of the game completely corrupted?
***If this is the scenario***, for how the game is intended so far, I still find difficult to think that something happen in a snap of a finger the day of the move, no matter how Sophia is corrupted. Yes, there was an interaction at the very beginning, but it was still in the realm of "flirting".
So, ***under these premises***, what if the movers, but let's say just Ivan to make it simple, would make the sporadic appearance throughout the FW route, without playing any major role of course, but just to make him/them witnessing Sophia's corruption, with Sophia obviously aware of their presence during her actions and, maybe, progressively enjoying the little "game" (cf the art class)? Or even with a minimum of interaction but without them being the main part of the event.
For example, let's say at some point one of the tasks is going to happen in public (e.g. another bar or similar) and again one or all of them are there to see (and being seen by Sophia). Again nothing happen with them, but it will build up the erotic tension that could be then triggered at the end during the moving.
I don't know if you were thinking something like that.
To me it would make sense having something like that, again, under the hypothesis that they won't be just moving furnitures at the end. It's just that I hope that, even when we will be well down the road of the corruption, the events will still have some reasonable build up and it won't just collapse in a dull fuckfest like other games.
And I know that in part it contradicts what L&P said, but he may not have told the "whole truth" to avoid spoiling too much
